284de7d957 adjust runtime page size APIs
* fix merge conflicts
* rename the declarations
* reword documentation
* extract FixedBufferAllocator to separate file
* take advantage of locals
* remove the assertion about max alignment in Allocator API, leaving it
  Allocator implementation defined
* fix non-inline function call in start logic

The GeneralPurposeAllocator implementation is totally broken because it
uses global state but I didn't address that in this commit.

5e1a83ad29 defaultPanic: @trap on 'other' target
The freestanding and other OS targets by default need to just @trap in the
default Panic implementation.

And `isValidMemory` won't work with freestanding or other targets.

Update the unwind_freestanding.zig test case to also run on the 'other' OS
target, too.  This should keep the Zig's stacktrace generation from
regressing on the standalone targets.

48d584e3a3 std.debug: reorg and clarify API goals
After this commit:

`std.debug.SelfInfo` is a cross-platform abstraction for the current
executable's own debug information, with a goal of minimal code bloat
and compilation speed penalty.

`std.debug.Dwarf` does not assume the current executable is itself the
thing being debugged, however, it does assume the debug info has the
same CPU architecture and OS as the current executable. It is planned to
remove this limitation.
